Bug ID: 54865
           Summary: ieframe:webbrowser sometimes gets
                    Invoke_PROPERTYCHANGE failures on Windows
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ieframe

ieframe:webbrowser sometimes gets Invoke_PROPERTYCHANGE failures on Windows:

The same failures happen in "Testing WebBrowser(no olecmd)...".
See https://test.winehq.org/data/patterns.html#ieframe:webbrowser
These failures happened regularly from 2022-11-01 to 2022-12-20 on Windows 10
1809 to 21H1. They also happened almost systematically on w1064v21h2 from
2022-11-21 to 2023-01-16. They also happened once on 2023-01-16 on w1064
(22h2).
And they stopped happening until ~3 months later: 2023-04-11 and now they
happened 4 times in a week.
So it's unclear what is causing these failures. There is no obvious change in
the test but it may be interference from another test, or something that causes
Windows to suddenly act differently (updates are disabled though).
Are these unexpected Invoke_PROPERTYCHANGE calls something the test should be
able to deal with?
